Mounting, Electrical, GAS Piping

INSTALLATION

Do not locate either the gas or electrical supply line directly over the top of the heater, due to the extreme heat that may cause overheating or damage. The heater must be installed in a location that is accessible for service. The heater must be installed in a way that doesn’t restrict fresh airflow to the unit. The heater cannot be installed in a recessed area. Doing so may cause poor performance and heat damage to the surrounding area.

MOUNTING

Each heater must be installed so that the minimum clearance to combustibles are maintained. Combustible materials are defined as wood, paper, foliage, plastic, plexiglass or other materials capable of being ignited and burned. Such materials shall be considered combustible even though flame-proofed, fire retardant treated or plastered. Additional clearances may be required for glass, painted surfaces and other materials which may be damaged by radiant or convection heat.

ELECTRICAL

Important!

A 24 VAC, 40 VA transformer has been included with the product. It is imperative to use this transformer.

The on-off control of the heater should be controlled from 120 VAC side of the transformer (see wiring diagram). A UL approved outdoor wall switch must be used for this purpose. The transformer must be mounted a minimum of 12” from the heater in a weather protected cover. Do not put the transformer in the heater or above the heater (this will damage the unit.) A step down transformer approved as having at least a 40 VA rating must be utilized for each connected heater. Control wires used to electrically connect one or more heaters together must have both adequate capacity and insulation temperature ratings for the total connected load. Use at least 18 ga. wire up to 50 ft. from heater to transformer or wall switch. Use 16 ga. over 50 ft. distance. If the original wires supplied should need replacement, they must be replaced with wiring material having a temperature rating of at least 105 degrees Centigrade/221º Fahrenheit.

GAS PIPING

A minimum pipe size of 1/2” is required for inlet piping. A 1/2” lever handled shut-off gas cock should be installed within 6 feet of the appliance for servicing the unit. Check with local and state plumbing and heating codes regarding sizing of the gas lines. Installation of a drip leg in the gas supply line going to each heater is required to minimize the possibility of any loose scale or dirt within the gas supply line from entering the heater’s control system. A 1/8” NPT plugged test gage connection is required immediately upstream of the gas supply connection to the heater.
